Hamlet Online
Here's a good example of the effective use of technology, taking advantage of what it does best!
Stephen Downes drew my attention today to the release of a free website called HamletWorks.org
The website is a work in progress, containing only half of the material the group has available at the moment, but the objective is to develop a database that will allow you to read around 400 years of commentary on Shakespeare's Hamlet - line by line! ( A printed variorum of Hamlet published in 1773 spanned 10 volumes, he says; by 1821 it had reached 21 volumes.)
For more background on the project take a look at the article in the Chronicle of Higher Education
